Power Dynamics in an Experimental Game 总被引:1,自引:1,他引:0
We introduce a new experimental method for studying power. Drawing from multiple theoretical perspectives, we conceptualize
power as relational and structural, as well as comprised of different forms through which basic human needs can be met. Thus,
the method we introduce examines how, when faced with a particular need, people use multiple forms of power concurrently and
within a “field of influence,” namely, the other players in a game. This enabled us to examine how one form of power is transformed
into another and how power is transferred from one player to another through interaction, as well as to measure power as behavior,
as the exercise of choice, as potential, and as outcomes. Two experiments using egalitarian start conditions and a survivable
ecology demonstrated that participants used power to gain more power, creating inequality. Being the target of force made
some players unable to “survive” in the local ecology. Theoretical and methodological issues in the study of power are discussed
and the application of our game method to the study of power in other fields is considered. 相似文献

Background. There have been a number of developments in the assessment of dynamic risk in the criminological literature. The dynamic risk assessment and management system (DRAMS) has been developed to facilitate the measurement of dynamic factors of risk for offenders with intellectual disability. Method. The study was designed to assess the construct validity, reliability and predictive utility of the DRAMS in 23 male forensic patients in a high secure setting. Predictions were made against independently collected incident data. Concurrent validity was assessed against the Ward Anger Rating Scale (WARS). Results. A reformulation of the individual section variables according to convergent and discriminant correlational analysis revealed Cronbach's alpha levels of >.8 for all sections apart from mood (alpha .750) and items retained to facilitate clinical information (alpha ?.017). Two hundred pairs of WARS and DRAMS assessments revealed orderly sectional correlations. The sections of mood, antisocial behaviour, and intolerance/agreeableness predicted incidents with a medium effect size as did total DRAMS score. There were highly significant differences between assessments taken 1 or 2 days prior to an incident and control assessments conducted at least 7 days from an incident. Conclusions. The reformulated DRAMS has good construct and concurrent validity. It appears to be a reliable assessment tool and informs on risk levels relating to stable and acute proximal factors. It appears as an important addition to the utility of risk assessments for this population. 相似文献

Martha Joynt Kumar is a professor of political science at Towson University. Her book, Managing the President’s Message: The White House Communications Operation (Johns Hopkins University Press, 2007), examines the media and communications operations of the administrations of Presidents Bill Clinton and George W. Bush. In March 2008, Professor Kumar was interviewed in the White House Press Briefing Room by Kevin R. Kosar on behalf of Public Administration Review. As this interview went to press, the American Political Science Association’s Presidency Research Group announced that it had awarded Managing the President’s Message the Richard E. Neustadt Award for best book on the U.S. presidency published in 2007. 相似文献

This article conceptualizes and analyses a type of complex social organization consisting of heterogeneous organizing modes and social relationships, combining, for instance, relationships making up markets and hierarchies as well as various types of informal networks. Each mode is constituted and regulated on the basis of a system of social rules making up a particular normative order and operates in terms of its own particular rationality or social logic. When modes are combined or integrated into multi-institutional complexes or organizations, the resultant structure entails zones of incongruence and tension at the junctures or interfaces of the different organizing modes and social relationships. The article identifies a number of such incongruent organizing modes that are common in complex social organizations or inter- institutional complexes. It goes on to identify several of the institutional strategies and arrangements including rituals, non-task-oriented discourses, and mediating roles that actors develop and institutionalize in dealing effectively with incongruences and potential conflicts in complex, heterogeneous organizations. The article suggests that problems of structural incongruence - and the tensions and conflicts that arise in connection with it as well as responses to these - are major features of complex organizational and inter-institutional arrangements. Moreover, it suggests that social order - the shaping of congruent, meaningful experiences - in these complex organizations as in most social life builds on non-rational foundations such as rituals and non-instrumental discourses. These contribute to maintaining social order and to providing a stable context, even for rational decision-making and action. 相似文献

In 16 medical examiner's cases, which were found to be barbiturate-positive by thin-layer chromatographic screening of the liver, blood barbiturate concentrations were determined by gas chromatography. The corresponding vitreous humor samples were screened by the enzyme multiplied immunoassay technique, the EMIT-st serum barbiturate assay. By using the recommended dilution for detecting serum barbiturates, it was possible to detect barbiturates in vitreous humor at a toxic concentration. By using one fourth the amount of diluent, the barbiturates could be detected also at a therapeutic concentration. The EMIT-st assay proved to be useful in the screening for barbiturates in vitreous humor, a material that is readily available in forensic toxicology. 相似文献

Conventional wisdom suggests that individual members of Congress have no real incentive to act in ways that might improve public evaluations of their collective body. In particular, the literature provides no clear evidence that public evaluations of Congress affect individual races for Congress, and little reason to expect that voters would hold specific individuals responsible for the institution's performance. We suggest that this conventional wisdom is incorrect. Using multiple state‐level exit polls of Senate voting conducted by Voter News Service in 1996 and 1998, we arrive at two key findings. First, we find that evaluations of Congress do have a significant effect on voting within individual U.S. Senate races across a wide variety of electoral contexts. Second, we find that punishments or rewards for congressional performance are not distributed equally across all members, or even across members of a particular party. Instead, we find that the degree to which citizens hold a senator accountable for congressional performance is significantly influenced by that senator's actual level of support for the majority party in Congress, as demonstrated on party votes. 相似文献

Summary statistics Measure of law firm prestige
- The article investigates the relationship betweenpricing in an initial public offering (IPO) and the prestigeof the participating underwriters law firm.
- The hypothesisof the article is that law firm quality affects how law firmsperform their obligations in IPOsmore prestigious lawfirms acting more independently. Consistent with this hypothesis,the authors find a negative relationship between pre-IPO priceadjustment and the participation of prestigious underwriterscounsel, and a negative relationship between the participationof prestigious underwriters counsel and initial return,which is consistent with market trading reflecting the decreasedrisk associated with offerings involving prestigious underwriterscounsel.
- Finally, it is found that certain observable characteristicsindicating diminished likelihood of undisclosed negative information(venture backing and quality of the issuer's counsel) are associatedwith an increased likelihood that prestigious underwriterscounsel is used.
